Back in the old days, video games were generally way tougher. Though most of them could be completed in an hour or two if you knew what to do, that usually wasn't the reality; you fumbled your way through them for entire days and weeks because they demanded such an intense amount of precision and skill. In the best games, this was rewarding. In the worst, infuriating.

One of this month's free PS4 games for PlayStation Plus subscribers is a throwback to that era in an incredible way. Meet "Furi."

In "Furi," you play as a nameless, silent swordsman who has been imprisoned under mysterious circumstances in a fantastical, sci-fi world. At the beginning of the game, you're freed by a guy in a rabbit costume who explains the story to you along the way.

Put simply, "Furi" is a game about fighting bosses. You fight a series of wonderfully distinctive bosses, which all behave completely differently, with each fight lasting quite a while. Sometimes, the game is played from an overhead perspective, where you can shoot an automatic pistol or slash with your sword...

...but in other situations, the game zooms in and you enter more of a duel phase, where you move more slowly and there's an added emphasis on swordplay. In both phases, you'll need to use quick reflexes and pattern memorization to dodge, parry and get your hits in where you can. It's exhilarating.

You've probably noticed by now that "Furi" has quite a look to it. Each fight takes place in a completely different environment, and most of them are so cool-looking that they would make excellent desktop backgrounds.

Visually, the best moments come in between the fights, as you slowly walk through gorgeous locales as your mysterious rabbit friend tells you a bit about who you're about to fight. Just look at this place!

And then this place! "Furi" is one of the most beautiful games that's come out in 2016, as you can see.

Each of the bosses in "Furi" was designed by "Afro Samurai" artist Takashi Okazaki, and they're all unique. For example, this one is a sniper who targets you from afar as you try to dodge an array of drones and traps she's set up to take you down.

This one, on the other hand, splits himself up into several copies and attacks you with poisonous gas. The only constant in "Furi" is that each boss will make you sweat, clench your teeth, curse a little bit and then raise your first in the air when you defeat them. It's amazingly rewarding.

"Furi" can be completed in just a few hours with enough patience and skill, and there is an easy mode for people who can't hang with the brutal default difficulty. The story isn't mindblowing or anything, but it's just solid enough to keep you interested as you work your way through its rogues' gallery of boss fights.
